Looking for some help as I have been spinning my wheels as to why my sons 300ex is making a screeching/whining noise when starting up. Any help would be appreciated. I thought it was the starter, but the starter sounds fine when not connected to the gears. I thought it was the one way starter bearing, so I replaced it and still have the sound. I have a video of the sound but cant seem to find a way to upload it.

Thanks

Andrew

Bearing sound? Grinding sound? Change w/temp or cold vs. warmed up? How long before it goes away? Throwing out ideas here.

Welcome to the forums!

My money would be on the starter still being the cause. Removing it and spinning it with zero resistance dosnt really say its good. But before i was 100% i would check the idler gears and bearings in the side case that make the connection to the starter clutch gear. Since you changed that already my money is still the starter though. My .02

Thanks for the replies so far.

The sound happens whether its cold or warm, basically always on start up. Maybe sounds a little worse when its cold.

Is there anyway to attach a movie file or sound file? I have the sound recorded on my phone and its probably best for you to hear it.

Remove and lubricate every possible area of the starter. Teeth, gears, shaft,everything. Until you can figure out how to load video, I’m out of suggestions.
